To all whom may concern:

Be it known that l, MARK 5.. Ross, a citizen of United States, residing at Chie more, in the county or Cool: and titote lllinoi. have invented a certain new and useful ,morovemcnt in Electric Headlights,

oil which the following is e specification.

My invention relates to electric headlights particularly intended for switch engines and for employment of incandescent lumps.

' ltis illustrated in the accompanying drawwherein Figure l; is oside elevation with p broken away and 'il ig. 2 is e detail. cross .5 tion. t

Like ports are indi tors in both figures it is base carrying; the bracket. l3 on which is mounted the reflector C.

J is 2, standard on the hose to which the reflector is secured at E.

F is a izo'np'stenderd on the base G which standard is rovidcd with at large zu er tore ll.

."Ql by the same lot l bolt which es through the base A and though the crture it and 1S cei d into the tliuinbsiut d Williill is provided with tile large flange overlying the iiderd are projections led with binding post ll t'tiilll O therefor. The inleading ion ected to theoctside of 'ng post-s, to the inside connected one of the flexible con which lead to the tube 8 mountof the lamp standard. 21 thumb th ew whereby this tube is "y screwed in position,

p recruited on the upper end.

soon the upper yer-e1 parts thus described csn, ct greatly changed 1n respect to size, and arrangement, but What it 1' end oi the lamp standard and securing it by means, of the thumbscrew in the desired position. The lamp may be adjusted in any direction in its horizontal plane by sliding the base of the lamp standard about and securing it in position by the thumbscrew and bolt.

The employment of'bindin posts on the lamp standard makes it possible-to emplo very short flexible Wires to lead from sucli binding posts to the tube. This is importent, "because the vibration to which such a device is subjected tends to break these necessarily flexible connections, but if these flexible conductors are short and arranged as here shown, this danger is substantially obmted. The inleading Wires, though more or less flexible, are heavy and not liable to injury from the vibration of the locomotive.

I claim: I

1. lo a locomotive headlight the combination of a reflector base and a reflector mounted thereon with a lamp standard providai w th a standard base having a large per n and a thumonut and a connecstander-o its mounted on the base and adjust- I able in any 6 rection thereon, a lamp socket vertical] at tobly mounted on the standard and e lamp mounted in the socket.

lo a, locomotive headlight the combina tion of e. reflector base and, a reflector mounted thereon with. e lamp standard provided with a stands d base having a largepertorstion and a thumb-nut and, a connec' tion from the thumb-nut to the reflector base through the perforation whereby the lamp etendord is laterally adjustably mounted on the base, o lamp socket verticslly adjustehly mounted on the standard and a lamp mounted in the socket, binding posts on the lamp standard and short flexi ble conductors leading from the binding posts to the lamp socket.

3. lo a locomotive headlight the combination of a reflector base and a reflector mounted thereon with a lamp standard laterally ediustably mounted on the base, alump socket vertically odjustably mounted on the standard, binding posts mounted on the standard, short flexible conductors leading from the binding post to the socket and a. lamp mounted. in the socket.

lo :1 locomotive headlight the combination of o reflector base and e reflector mounted on thebase and adjustable in any direction thereon, a 1am socket vertically adjustnb'ly mounted on t e standard and 'e' lamp mounted inthe socket, binding posts on the standard and short flexible conductors leading from the binding posts to the lamp sockets. I

5. In a locomotive headlight the combination of a reflector base-11nd a reflector mounted thereon with a lamp standard mounted on the base, a lamp socket vertically adjustabiy mounted on the standard and 21 1am mounted in the socket, the

standard being adjustable on the base iiide- 15 MARK- A. Ross.
